Highlights: Hello and welcome to our new post. In this lecture, we will continue gaining a good understanding of the image formation process. In particular, we are going to talk about how we can project a 3D scene onto a 2D image. We will introduce basic primitives and transformations in conventional but also in so-called homogeneous coordinates which play a fundamental role in describing objects and projections in 3D computer vision. Once we have an…

Highlights: Hello, and welcome. In this post, we’re going to talk about how to form an image from a 3D scene onto a 2D plane. We will start with a concept of a pinhole camera which is one of the most important concepts in computer vision. It is the simplest type of camera that you can imagine and it performs perspective projection. In this post, we are going to review the YouTube video “Pinhole and…

Highlights: Hello and welcome. Today we will continue our series of posts about 3D face modeling. In this post, we are going to talk about parametric face model tracking and reconstruction. In the previous posts, we talked about how to create a parametric face model. Now, let’s talk about what we can do once a face model is created. More specifically, how can we reconstruct a face from an image into a 3D form (3D…
